In this paper, an adaptive control method for target-enclosing strategies is considered. The proposed enclosing control strategy achieves enclosing configurations based on virtual structures. We assume that there exist an uncertainty in the information exchange topology between an agent and all of its neighbors on the network. We regard that the uncertainty in the information exchange topology can...
This paper describes identifying Tactile Walking Surface Indicators (TWSIs) with a white cane using an accelerometer. The vibration was examined by using an actual dot block. The effectiveness of the white cane was verified by examining the relation between the vibration and psychological strength. The experiment result revealed that there is no correlation between the psychological distance and the...
Fully integrated electric propulsion systems are gaining popularity in both commercial and military sectors. Propulsion motor manufacturers are investigating new direct drive solutions for use in electric ships. These applications require motors with high torque output at low speeds. Such requirements were the motivation for the design of a new PMSM with a novel topology. Firstly, this paper describes...
In the holographic 3D display using mist screen, large 3D images can be observed with wide viewing angle. However, in the previous methods, it was difficult to observe the sides of the projected 3D images. In this paper, we studied a process to expand the displaying volume of the projected 3D images by preparing a jetting system improving the characteristics of the mist screen and by combining the...
It is an important issue that the relationship between personality and individual characteristic of an electroencephalogram (EEG) for using a personalized brain computer interface on daily basis. In this paper, we introduce a method for discussing the relationship between personality based on egogram scores and the results of the EEG pattern detection. The egogram based on psychological testing is...
In this paper, the low-profile radiation-pattern controllable antenna is presented. The diskloaded monopole antenna (DLMA) with four slits is designed for low-profile radiation element. And, planar CRLH-PE composited of the mushroom structures is designed. It is cleared that the DLMA and the CRLH-PE with the height of 0.03λ at 750 MHz can couple each other. The radiation patterns can be controlled...
This paper presents an unsupervised segmentation method using hybridized Self-Organizing Maps (SOMs) and Fuzzy Adaptive Resonance Theory (ART) based only on the brightness distribution and characteristics of head MR images. We specifically examine the features of mapping while maintaining topological relations of weights with SOMs and while integrating a suitable number of categories with Fuzzy ART...
We propose an objective segmentation method for Magnetic Resonance (MR) images of the brain using self-mapping characteristics of one-dimensional Self-Organizing Maps (SOM). The proposed method requires no operators to specify the representative points, but can segment tissues (such as cerebrospinal fluid, gray matter and white matter) needed for diagnosis of brain atrophy. Doing clinical image experiments,...
We propose an inter-domain path routing algorithm for multi-domain photonic networks that uses inexact traffic information of each domain. Proposed method almost matches the blocking probability of a method that utilizes all existing path information.
In order to deal with ultra multi degree-of-freedom (DOF) dynamical systems, this paper proposes a design methodology for a control scheme inspired by the concept of emergence in living organisms. With this methodology, specific functions are found to appear in the system only using only local information available to the subcomponents of the system. In order to introduce the advantages of emergence...
We propose a novel dynamic hierarchical optical path network architecture and operation algorithms. Operational and facility costs are significantly reduced by the adaptive direct connections made possible by highly granular waveband paths.
This paper presents advantageous features of the distributed traction systems, or Electric Multiple Units, and application of power electronics technology to the Shinkansen High-speed train. The EMUs have many advantages such as the energy saving by regenerative brake, high-speed running on steep gradient routes with high adhesive force, and others. Historically, the Japanese highspeed train system,...
This paper presents a double DC-DC converter for uninterruptible power supply applications. The converter has a simple structure and is applied to a high capacity uninterruptible power supply (UPS). In comparison with a conventional DC-DC converter, a double DC-DC converter exhibits lower ripple current and offers many benefits to UPS systems such as size/weight reduction and higher efficiency. The...
Flip chip bonding requires a device to be flipped and attached to the bond pads or traces on the substrate. For lower pitch devices with large bond pads, this was accomplished using gravity reflow followed by capillary underfill (CUF). For fine-pitch devices mounted close to each other on a substrate, CUF has not been as effective as the use of a Non-conductive paste (NCP) during Thermal Compression...
Advances in silicon technology are failing to keep up with Internet traffic; this is unfortunate since we can envisage large bandwidth video distribution services carrying super-/ultra- high definition videos. In this context, optical technologies are critical to create bandwidth-abundant and power-efficient networks. Future networks will utilize optical paths not only for network implementation but...
A 10-Gb/s Mach-Zehnder modulator is monolithically integrated with a tunable laser source based on a 2-ring loop-filter with a small device dimension (2.5 × 0.9 mm2). Sufficient static extinction ratio of 16.5 dB was obtained both at 1573.92 and 1595.50 nm.
Light speed mode de-multiplexing is demonstrated by 3-dimentional phase matching for multiple spatial modes through holographic multiplexing technique. Separating of around 60-70% was achieved in experiments of separating multiplexed three modes by dynamic reconfigurable diffraction.
In order to realize very high throughput wireless local area network (WLAN) systems, which demand multi Gbps capacities/bitrates, IEEE802.11ad (next generation WLAN standard in the 60GHz band) is in the standardization process. To evaluate the physical layer modulation and coding schemes in the standardization process, channel models in each specified environment are required. In this paper, propagation...
In this work, segmentation is an intermediate step in the registration and 3D reconstruction of the lung, where the diaphragmatic surface is automatically and robustly isolated. Usually, segmentation methods are interactive and use different strategies to combine the expertise of humans and computers. Segmentation of lung MR images is particularly difficult because of the large variation in image...
We have proposed an adaptive control scheme for systems with input saturation. In the conventional scheme, a restrict condition for initial states of the closed loop system has to be satisfied. In the paper, the main attention is to relax the restrict condition for initial states. As a result of reanalyzing stability of the closed loop system, we have a new condition for initial states. Namely, using...
